All these guys doing technical data driven reviews have very technical backgrounds. What I have gathered from watching Erin’s channel is he is a “Rocket scientist” focused on systems testing under contract (indirect probably) as he is not allowed to talk about his work. I have friends in a similar fields that are also not allowed to discuss their work for obvious reasons.
Gene from audioholics and Amir from ASR have telecommunications backgrounds or some kind I think. They have stated before where and what they worked on but I can’t remember.
Anyway it is irrelevant but these are all very smart people as this hobby attracts a certain type of personality IMO.
